For noun it is tsismis, it is a Pinoy word for gossip. Literally tsismising in English is gossiping (verb). It is for some Filipinos most common behavior, to tattle and tattle nuisance about nonsense talks.

ORIGIN and LEGEND: Tsismising was originally vogued by DOM Professor from one of the University in the Philippines (University Belt, Manila), when he spotted and scold one of his student at the back area of the room. He became popular because of his ridiculous talks and because of that tsismising became a craze in one of the university in Intramuros. And until that time, it was infectiously spread all over the campus and surprisingly from all University around Manila.

Prof. DOM DONATO: "WHAT THE !@#$ ! YOU AT THE BACK! YOU'RE TSISMISING AGAIN MR.POGI WHILE I'M TEACHING HERE! HOW RUDE YOU SHOWING ME WITH NO RESPECT! I'LL REPORT YOU TO SOG... GRRR, OR PERHAPS I'LL CALL A GUARD!"
